Pressure generator/gas scrubber

Abstract

A pressure generator and gas scrubber includes a scroll casing having a gas discharge outlet and a plurality of liquid outlets; a hollow shaft extending through the casing for supplying water thereto; a plurality of radially-extending water feed tubes centrally positioned in the casing and secured to the hollow shaft in fluid communication therewith, each tube having an open outlet end at the free end thereof such that liquid supplied through the hollow shaft travels to the open outlet ends of the feed tubes and each tube having a constricted opening at the open outlet end thereof; a drive motor connected to the hollow shaft for rotating the hollow shaft and the plurality of feed tubes; and two gas inlet boxes positioned on opposite sides of the scroll casing in fluid communication with a central portion of the casing, for supplying a contaminated gas to be scrubbed to the casing adjacent the inlet ends of the feed tubes, such that water jets ejected from the open outlet ends of the feed tubes pull the gas adjacent the inlet ends into scrubbing contact with the water and create a positive pressure.

I claim: 
     
       1. Apparatus for generating pressure and scrubbing gas comprising: a casing having a scroll casing;   a gas outlet, tangential to and in fluid communication with said scroll casing, and at least one liquid outlet;   rotating means for generating a positive pressure and for scrubbing gases supplied to said casing, said rotating means including a plurality of radially extending feed tubes positioned in said scroll casing, each tube having an open outlet end and an inlet end;   liquid supply means for supplying liquid to said inlet ends of said feed tubes;   said casing further comprising gas inlet supply means for supplying a gas to said casing at a position adjacent said inlet ends of said feed tubes, wherein said gas supply means includes at least one gas inlet box positioned on one side of said scroll casing and in fluid communication with a central portion of said scroll casing, each said gas inlet box including a gas supply inlet; and   drive means for rotatably driving said rotating means such that said liquid exiting from said feed tubes rotates along a peripheral arc of said scroll casing, and said gas outlet is located in said scroll casing substantially along a tangent to said peripheral arc, wherein said liquid ejected from said open outlet ends of said feed tubes pulls said gas adjacent said inlet ends into scrubbing contact with said liquid and results in formation of said positive pressure at the gas outlet of said casing, with said scrubbed gas exiting through said gas outlet and said liquid exiting through said at least one liquid outlet.   
     
     
       2. Apparatus according to claim 1, wherein said gas supply means includes two gas inlet boxes, each including a gas supply inlet, said gas inlet boxes positioned on opposite sides of said scroll casing and in fluid communication with a central portion of said scroll casing. 
     
     
       3. Apparatus according to claim 1, wherein said liquid supply means includes a hollow shaft extending into said casing, said inlet ends of each said feed tube being secured to said hollow shaft and in fluid communication therewith, said feed tubes extending radially from said hollow shaft. 
     
     
       4. Apparatus according to claim 3, wherein said feed tubes extend equiangularly around said hollow shaft. 
     
     
       5. Apparatus according to claim 3, wherein said drive means includes a drive motor connected with said hollow shaft for rotating said hollow shaft about its axis. 
     
     
       6. Apparatus according to claim 3, wherein said drive motor is connected with one end of said hollow shaft, and said liquid supply means further includes a stationary liquid supply pipe connected in a rotatably, sealed manner to an opposite end of said hollow shaft. 
     
     
       7. Apparatus according to claim 1, wherein said outlet end of each said feed tube includes an outlet opening for emitting said liquid in an axial direction of said feed tubes. 
     
     
       8. Apparatus according to claim 7, wherein each of said feed tubes includes a through passageway having a first dimension, and said outlet end of each said feed tube includes a constriction which reduces said outlet opening to a dimension less than said first dimension. 
     
     
       9. Apparatus according to claim 8, wherein said outlet end of each said feed tube is tapered to form said constriction. 
     
     
       10. Apparatus according to claim 1, further including disc means for substantially reducing rotation of said gas which occurs by reason of said plurality of feed tubes, said disc means being secured to said rotating means. 
     
     
       11. Apparatus according to claim 10, wherein said disc means includes a first disc secured to one side of said feed tubes and a second disc secured to an opposite side of said feed tubes. 
     
     
       12. Apparatus according to claim 1, wherein said gas inlet supply means includes means for supplying said gas to said casing only at a position adjacent said inlet ends of said rotating means.
